No. They do not respire, metabolise, grow or excrete.
Viruses do not breathe because they are not living organisms. They are considered particles that need a host cell to replicate and survive. Once a virus infects a host cell, it uses the cell’s machinery to replicate itself.
A human can contract hanta virus (a respitory virus) if they breathe the air around infected mouse feces that has been in a contained area.
You can get viruses through contact and through the air. The cells of Mucous membrane, such as those lining the respiratory passages that we breathe through, are open to virus attacks because we breathe the air and we can't stop breathing or we die. We also don't know who might have it and we could walk by someone who sneezed/coughed and getinvectived.
Because you have a stuffy nose when you get a cold.
A virus can enter the body in different ways, like when we breathe in tiny droplets from someone who is sick or touch surfaces where the virus has landed. Once inside, the virus finds a way to get into our cells, which are like tiny building blocks of our body. It then makes copies of itself, which can make us feel unwell. That's why it's important to wash our hands and stay away from sick people!
You can pass a cold through respiratory droplets when an infected person talks, coughs, or sneezes, spreading the virus to others who breathe in the droplets. The virus can also spread by touching surfaces contaminated with the virus and then touching your face.
Recently it has been seen that this virus directly attack on your respiratory system, and when this virus comes on its next stage it becomes difficult to breathe as it blocks your caves from where you inhale.So in yoga there is some breathing exercises that will power your lungs, and it will streghten your respiratory system.There is much yoga breathing exercise you can try such as Kapalbhati and Belly Breather.
Viruses are not living things because they do not meat the definition/standard science uses to define living things.
its what you breathe and what plants breathe out while they breathe that out they breathe in carbon diOxide and we breathe it out.
The virus that causes chicken pox is not considered a living organism because it does not possess the characteristics typically associated with life. It cannot reproduce independently, does not metabolize nutrients, nor does it exhibit cellular structure or functions. Instead, it relies on hijacking the cellular machinery of living hosts to replicate and propagate itself. Thus, it is classified as a virus, which is distinct from living organisms.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.
